2017 Ram ProMaster warning light

ESC Partial Off
This mode is entered by momentarily pushing the “ESC
Off” switch.
When in the “Partial Off” mode, the TCS portion of ESC,
except for the “limited slip” feature described in the TCS
section, has been disabled and the “ESC OFF Indicator
Light” will be illuminated. When in the “Partial Off” mode,
ESC will operate without engine torque management. This
mode is intended to be used if the vehicle is in deep snow,
sand or gravel conditions and more wheel spin than ESC
would normally allow is required to gain traction. To turn
ESC on again, momentarily push the “ESC Off” switch.
This will restore the normal “ESC On” mode of operation.
WARNING!
•When in Partial Off mode, the TCS functionality of
ESC, (except for the limited slip feature described in
the TCS section), has been disabled and the ESC Off
Indicator Light will be illuminated. When in Partial
Off mode, the engine power reduction feature of
TCS is disabled, and the enhanced vehicle stability
offered by the ESC system is reduced.

WARNING! (Continued)
•Trailer Sway Control (TSC) is disabled when the ESC
system is in the Partial Offmode.
NOTE: To improve the vehicle’s traction when driving
with snow chains, or starting off in deep snow, sand or
gravel, it may be desirable to switch to the “Partial Off”
mode by pushing the “ESC Off” switch. Once the situation
requiring ESC to be switched to the “Partial Off” mode is
overcome, turn ESC back on by momentarily pushing the
“ESC Off” switch. This may be done while the vehicle is in
motion.
ESC Activation/Malfunction Indicator Light And
ESC OFF Indicator Light
The “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is turned to the ON
position. It should turn off with the engine
running. If the “ESC Activation/Malfunction Indicator
Light” comes on continuously with the engine running, a
malfunction has been detected in the ESC system. If this
light remains on after several ignition cycles, and the
vehicle has been driven several miles (kilometers) at

WARNING!
If TSC activates while driving, slow the vehicle down,
stop at the nearest safe location, and adjust the trailer
load to eliminate trailer sway.
Hill Start Assist (HSA)
The HSA system is designed to assist the driver when
starting a vehicle from a stop on a hill. HSA will maintain
the level of brake pressure the driver applied for a short
period of time after the driver takes their foot off of the
brake pedal. If the driver does not apply the throttle during
this short period of time, the system will release brake
pressure and the vehicle will roll down the hill. The system
will release brake pressure in proportion to the amount of
throttle applied as the vehicle starts to move in the
intended direction of travel.
HSA Activation Criteria
The following criteria must be met in order for HSA to
activate:
•Vehicle must be stopped.
• Vehicle must be on a 6% (approximate) grade or greater
hill. •
Gear selection matches vehicle uphill direction (i.e.,
vehicle facing uphill is in forward gear; vehicle backing
uphill is in REVERSE gear).
HSA will work in REVERSE and all forward gears when
the activation criteria have been met. The system will not
activate if the vehicle is placed in NEUTRAL or PARK.
WARNING!
There may be situations on minor hills with a loaded
vehicle, or while pulling a trailer, when the system will
not activate and slight rolling may occur. This could
cause a collision with another vehicle or object. Always
remember the driver is responsible for braking the
vehicle.
Towing With HSA
HSA will provide assistance when starting on a grade
when pulling a trailer.
WARNING!
• If you use a trailer brake controller with your trailer,
your trailer brakes may be activated and deactivated

Life Of Tire
The service life of a tire is dependent upon varying factors
including, but not limited to:
•Driving style.
• Tire pressure - Improper cold tire inflation pressures can
cause uneven wear patterns to develop across the tire
tread. These abnormal wear patterns will reduce tread
life, resulting in the need for earlier tire replacement.
• Distance driven.
• Performance tires, tires with a speed rating of V or
higher, and Summer tires typically have a reduced tread
life. Rotation of these tires per the vehicle maintenance
schedule is highly recommended.
WARNING!
Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire failure.
You could lose control and have a collision resulting in
serious injury or death. Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact with
oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressures. The manu-
facturer strongly recommends that you use tires equivalent
to the originals in size, quality and performance when
replacement is needed. Refer to the paragraph on “Tread
Wear Indicator”. Refer to the Tire and Loading Information
placard or the Vehicle Certification Label for the size
designation of your tire. The Load Index and Speed
Symbol for your tire will be found on the original equip-
ment tire sidewall. See the Tire Sizing Chart example found
in the “Tire Safety Information” section of this manual for
more information relating to the Load Index and Speed
Symbol of a tire.
It is recommended to replace the two front tires or two rear
tires as a pair. Replacing just one tire can seriously affect
your vehicle’s handling. If you ever replace a wheel, make
sure that the wheel’s specifications match those of the
original wheels.
216 STARTING AND OPERATING

It is recommended you contact your authorized tire dealer
or original equipment dealer with any questions you may
have on tire specifications or capability. Failure to use
equivalent replacement tires may adversely affect the
safety, handling, and ride of your vehicle.
WARNING!
•Do not use a tire, wheel size or rating other than that
specified for your vehicle. Some combinations of
unapproved tires and wheels may change suspen-
sion dimensions and performance characteristics,
resulting in changes to steering, handling, and brak-
ing of your vehicle. This can cause unpredictable
handling and stress to steering and suspension com-
ponents. You could lose control and have a collision
resulting in serious injury or death. Use only the tire
and wheel sizes with load ratings approved for your
vehicle.
• Never use a tire with a smaller load index or capacity,
other than what was originally equipped on your
vehicle. Using a tire with a smaller load index could
result in tire overloading and failure. You could lose
control and have a collision.
(Continued)
WARNING! (Continued)
•Failure to equip your vehicle with tires having ad-
equate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
TIRE CHAINS (TRACTION DEVICES)
Use of traction devices require sufficient tire-to-body clear-
ance. Follow these recommendations to guard against
damage.
• Traction device must be of proper size for the tire, as
recommended by the traction device manufacturer.
• Install on front tires only.
• Tire chains for a 225/75R16 tire with a Quality Chain
Corp Light Truck Highway Service (Non-Cam) tire chain
or equivalent is recommended.

STARTING AND OPERATING 217

The suggested rotation method is the “forward cross”
shown in the following diagram. This rotation pattern does
not apply to some directional tires that must not be
reversed.
TIRE PRESSURE MONITORING SYSTEM (TPMS)
The Tire Pressure Monitor System (TPMS) will warn the
driver of a low tire pressure based on the vehicle recom-
mended cold tire pressure.
The tire pressure will vary with temperature by about 1 psi
(7 kPa) for every 12°F (6.5°C). This means that when theoutside temperature decreases, the tire pressure will de-
crease. Tire pressure should always be set based on cold
inflation tire pressure. This is defined as the tire pressure
after the vehicle has not been driven for at least three
hours, or driven less than 1 mile (1.6 km) after a three hour
period. The cold tire inflation pressure must not exceed the
maximum inflation pressure molded into the tire sidewall.
Refer to “Tires – General Information” in “Starting And
Operating” for information on how to properly inflate the
vehicle’s tires. The tire pressure will also increase as the
vehicle is driven, this is normal and there should be no
adjustment for this increased pressure.
The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low pressure warning limit for
any reason, including low temperature effects, or natural
pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn
off until the tire pressure is at or above the recommended
cold tire pressure on the placard. Once the low tire pressure
warning (Tire Pressure Monitoring Telltale Light) illumi-
nates, you must increase the tire pressure to the recom-
mended cold tire pressure in order for the Tire Pressure
Monitoring Telltale Light to turn off. The system will

automatically update and the Tire Pressure Monitoring
Telltale Light will turn off once the system receives the
updated tire pressures. The vehicle may need to be driven
for up to 20 minutes above 15 mph (24 km/h) in order for
the TPMS to receive this information.
For example, your vehicle may have a recommended cold
(parked for more than three hours) tire pressure of 30 psi
(207 kPa). If the ambient temperature is 68°F (20°C) and the
measured tire pressure is 27 psi (186 kPa), a temperature
drop to 20°F (-7°C) will decrease the tire pressure to
approximately 23 psi (159 kPa). This tire pressure is suffi-
ciently low enough to turn on the Tire Pressure Monitoring
Telltale Light. Driving the vehicle may cause the tire
pressure to rise to approximately 27 psi (186 kPa), but the
Tire Pressure Monitoring Telltale Light will still be on. In
this situation, the Tire Pressure Monitoring Telltale Light
will turn off only after the tires are inflated to the vehicle’s
recommended cold tire pressure value.
CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warnings have been established for the tire size

equipped on your vehicle. Undesirable system op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an after-
market tire sealant it is recommended that you take
your vehicle to an authorized dealership to have your
sensor function checked.
• After inspecting or adjusting the tire pressure, al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the Tire Pressure Monitoring
Sensor.
NOTE:
• The TPMS is not intended to replace normal tire care and
maintenance, or to provide warning of a tire failure or
condition.
• The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
220 STARTING AND OPERATING

•Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Under-
inflation also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and stopping
ability.
• The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire gauge, even if
under-inflation has not reached the level to trigger
illumination of the Tire Pressure Monitoring Telltale
Light.
• Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in the
tire.
Base System
This is the TPMS warning indicator located in the
instrument cluster.
The TPMS uses wireless technology with wheel rim
mounted electronic sensors to monitor tire pressure levels.
Sensors, mounted to each wheel as part of the valve stem,
transmit tire pressure readings to the Receiver Module. NOTE:
It is particularly important for you to check the tire
pressure in all of the tires on your vehicle regularly and to
maintain the proper pressure.
The TPMS consists of the following components:
• Receiver Module.
• Five Tire Pressure Monitoring Sensors.
• Tire Pressure Monitoring Telltale Light.
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will illuminate
in the instrument cluster, an audible chime will be acti-
vated, and the “Check tire pressure” text message will
display when one or more of the four active road tire
pressures are low. Should this occur, you should stop as
soon as possible, check the inflation pressure of each tire on
your vehicle, and inflate each tire to the vehicle’s recom-
mended cold placard pressure value. The system will
automatically update and the Tire Pressure Monitoring
Light will extinguish once the updated tire pressures have
been received. The vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) to receive this
information.

STARTING AND OPERATING 221

Check TPMS Warnings
The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds and remain on solid when a system
fault is detected, an audible chime will be activated and the
“Tire Pressure Monitoring Unavailable” text message will
display. If the ignition key is cycled, this sequence will
repeat providing the system fault still exists. The Tire
Pressure Monitoring Telltale Light will turn off when the
fault condition no longer exists. A system fault can occur
with any of the following scenarios:
1. Jamming due to electronic devices or driving next tofacilities emitting the same radio frequencies as the TPM
sensors.
2. Installing some form of aftermarket window tinting that affects radio wave signals.
3. Snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
NOTE: Your vehicle is equipped with a regular size spare
wheel. 1. The spare tire has a tire pressure monitoring sensor, but
it is not monitored until it is mounted in place of any of
the existing four road tires.
2. If you install the spare tire in place of a road tire that has a pressure below the low-pressure warning limit, upon
the next ignition key cycle, a chime will sound and the
Tire Pressure Monitoring Telltale Light will turn ON due
to the low tire condition. Then, after driving the vehicle
for up to 20 minutes above 15mph (24km/h), the system
will recognize the new sensor, and turn off the telltale.
3. If a spare tire not equipped with tire pressure monitor- ing sensor is used, then the Tire Pressure Monitoring
Telltale Light will turn ON, flashing for 75 seconds and
then remaining solid for each subsequent ignition key
cycle.
NOTE: For correct Tire Pressure Monitoring behavior,
please wait for about 20 minutes in key-off during each tire
substitution.
